How the Circuit Works

The vehicle does not use a throttle cable or cruise control actuator to maintain the vehicle speed during the cruise control mode. A throttle actuator control motor, located on the side of the throttle housing, is used to open and close the throttle plate for routine driving and cruise conditions.

Power Supply

Battery voltage is supplied at all times through fuse 18 (in the under-hood fuse/relay box) to the ETCS control relay contacts, and through fuse 10 (in the under-hood fuse/relay box) to the horn relay and brake pedal position switch. Battery voltage is also supplied at all times through fuse 15 (in the under-hood fuse/relay box) to the gauge control module.

With the ignition switch in ON (II) or START (III) or the engine start/stop switch pressed to select ON or START mode, battery voltage is supplied through fuse 13 (in the driver's under-dash fuse/relay box) to the brake pedal position switch and then to the PCM and through fuse 5 (in the driver's under-dash fuse/relay box) to the gauge control module and then to the main switch of the cruise control combination switch.

System Description

When the main switch is pressed, a battery voltage input is removed from the gauge control module, and the cruise control main switch indicator LED illuminates. With the shift lever in D or S, a path to ground is provided for the drive input to the PCM. The PCM detects that the shift lever is in D or S through this input, which enables the cruise control.

When the set switch is pressed, a voltage signal is sent to the gauge control module. The gauge control module grounds the cruise control indicator LED, illuminating it. The gauge control module communicates the set signal via multiplex communication lines to the PCM. Using the vehicle speed input obtained from the output shaft (countershaft) speed sensor, the PCM sends signals to, and receives signals from, the TP sensor/throttle actuator, which opens and closes the throttle to maintain the set speed.

When the brake pedal is pressed, a battery voltage input is sent to the PCM through fuse 10 (in the under-hood fuse/relay box) and the battery voltage input through fuse 13 (in the driver's under-dash fuse/relay box) is removed. The PCM communicates the brake pedal pressed information via multiplex communication lines to the gauge control module, which removes ground from the cruise control indicator LED, turning it off. The information is also used by the PCM to remove the cruise control system's control of the throttle.

When the resume switch is pressed, a voltage signal is sent to the gauge control module. The gauge control module grounds the cruise control indicator LED, illuminating it. The gauge control module communicates the resume signal via multiplex communication lines to the PCM. Using the vehicle speed input obtained from the output shaft (countershaft) speed sensor, the PCM sends signals to, and receives signals from, the TP sensor/throttle actuator, which opens and closes the throttle to resume and maintain the previously set speed.

When the cancel switch is pressed, two voltage signals are sent to the gauge control module. The gauge control module removes ground from the cruise control indicator LED, turning it off. The gauge control module communicates the cancel signal via multiplex communication lines to the PCM. The information is also used by the PCM to remove the cruise control system's control of the throttle.

The multiplex integrated control system sends digital signals between control units through shared wires to reduce the number of wires in order to make harnesses lighter.

The input signals from each switch are converted to digital signals within the receiving control unit. The digital signals are sent from one control unit to another as serial data over dedicated communication lines. When the appropriate control unit receives the digital signal, it converts the signal back to an operational command, such as operating a relay. The multiplex integrated control system schematic shows its power, grounds, and communication lines.

There are two different networks within the multiplex integrated control system

1. Body Controller Area Network (B-CAN)
2. Fast Controller Area Network (F-CAN)

The body controller area network (B-CAN) and fast controller area network (F-CAN) share information between multiple electronic control units and work together to form the multiplex integrated control system. The gauge control module translates information from B-CAN to F-CAN and from F-CAN to B-CAN to allow the networks to share information.

B-CAN Network

B-CAN information is transmitted across the communication lines at a slower speed for convenience related operations that do not require a high process speed. The following systems are related to the B-CAN network

1. Audio System
2. Battery Management System

Fans Circuit Diagram (Page 63). Scheme 200

Battery voltage is supplied at all times through Multi-fuse 3 (in the under-hood fuse/relay box) to the contacts of the A/C Condenser Fan Relay and Radiator Fan Relay. With the ignition switch in ON (II) or the engine start/stop switch in ON, battery voltage is supplied through fuse 16 (in the driver's under-dash fuse/relay box) to the coils of the A/C Condenser Fan Relay and Fan Control Relay. With the engine running, battery voltage is supplied through fuse 21 (in the under-hood fuse/relay box) to the Radiator Fan Relay coil.

Extremely High Coolant Temperatures

In extremely high coolant temperature conditions (Above 206°F (97°C)), the PCM provides ground to the coils of the A/C Condenser Fan Relay, the Radiator Fan Relay, and the Fan Control Relay, energizing them. Battery voltage is supplied to the A/C Condenser Fan Motor and Radiator Fan Motor through their respective energized relays, which activates the motors at high speed.

A/CON

The PCM detects that the A/C is ON through an input from the A/C Pressure Sensor. Upon receiving the A/C ON information, the PCM provides ground to the coil of the A/C Condenser Fan Relay, energizing it. Battery voltage is supplied to the A/C Condenser Fan Motor and Radiator Fan Motor in series through the energized relay, which activates the motors at low speed.

If the refrigerant pressure rises above 1470 kPa (213 psi), the A/C Pressure Sensor signals the PCM to run the fans at high speed. The PCM provides ground to the coils of the A/C Condenser Fan Relay, the Radiator Fan Relay, and the Fan Control Relay, energizing them. Battery voltage is supplied to the A/C Condenser Fan Motor and Radiator Fan Motor through their respective energized relays, which activates the motors at high speed.

Refrigerant at Low Pressure

If the refrigerant pressure drops below 196 kPa (28 psi), the A/C Pressure Sensor signals the PCM to turn off the fans. Upon receiving the signal to turn off the fans, the PCM removes ground from the coil of the A/C Condenser Fan Relay, de-energizing it. This removes battery voltage from the A/C Condenser Fan Motor and Radiator Fan Motor, which deactivates the motors.

Refrigerant at High Pressure

If the refrigerant pressure rises above 3138 kPa (455 psi), the A/C Pressure Sensor signals the PCM to turn off the fans. Upon receiving the signal to turn off the fans, the PCM removes ground from the coils of the A/C Condenser Fan Relay, the Radiator Fan Relay, and the Fan Control Relay, de-energizing them. This removes battery voltage from the A/C Condenser Fan Motor and Radiator Fan Motor, which deactivates the motors.

Refer to the FAN CONTROLS for specific tests and troubleshooting procedures.

Rear Window/Power Mirror Defoggers Circuit Diagram (Page 64-1). Scheme 202

Rear Window Defogger

Battery voltage is supplied at all times to the Rear Window Defogger Relay contacts through fuse 8 (in the under-hood fuse/relay box). With the ignition switch in ON (II) or the engine start/stop switch in ON, battery voltage is supplied to the Rear Window Defogger Relay coil and to the Climate Control Unit through fuse 16 (in the driver's under-dash fuse/relay box).

When the Rear Window Defogger Switch/Mirror Defogger Switch (in the Audio-Navigation and HVAC Switch Panel, or the Audio and HVAC Switch Panel) is pressed, the defog signal is sent to the Driver's MICU. The Driver's MICU provides ground to the Rear Window Defogger Relay coil, energizing the relay. Battery voltage is supplied to the Rear Window Defogger through the energized relay.

The Rear Window Defogger is turned off by pressing the Rear Window Defogger/Mirror Defogger Switch a second time or by turning the ignition switch to LOCK (0) or the engine start/stop switch to OFF.

Power Mirror Defoggers

Battery voltage is supplied at all times to the Front Passenger's Power Window Switch through fuse 13 (in the passenger's under-dash fuse/relay box). With the ignition switch in ON (II) or the engine start/stop switch ON, battery voltage is supplied to the Power Window Master Switch and to the HVAC Control Unit or Climate Control Unit through fuse 16 (in the driver's under-dash fuse/relay box).

When the Rear Window Defogger Switch/Mirror Defogger Switch (in the Audio-Navigation and HVAC Switch Panel, or the Audio and HVAC Switch Panel) is pressed, the defog signal is sent to the Power Window Master Switch via B-CAN and then to the Front Passenger's Power Window Switch via UART. The Power Window Master Switch supplies battery voltage to the Left Power Mirror Defogger and the Front Passenger's Power Window Switch supplies battery voltage to the Right Power Mirror Defogger.

The Power Mirror Defoggers are turned off by pressing the Rear Window Defogger Switch/Mirror Defogger Switch a second time or by turning the ignition switch to LOCK (0) or the engine start/stop switch to OFF.

Refer to the REAR WINDOW DEFOGGER for specific tests and troubleshooting procedures.

Wiper/Washer Circuit Diagram (Page 91-2). Scheme 224

The wiper/washer system is part of the multiplex integrated control system. The Driver's MICU, Passenger's MICU, and the Windshield Wiper/Washer Switch are the main operation controls of the wiper/washer system. The Wiper Motor Relay, Wiper Intermittent Relay, and Wiper High/Low Relay are incorporated in the Under-hood Fuse/Relay Box.

Testing of the multiplex components and reading Diagnostic Trouble Codes (DTCs) can be done by using an HDS Tester. The Windshield Wiper Motor and Windshield Washer Motor also can be tested manually without an HDS Tester.

Refer to the WIPER SYSTEM / WASHER SYSTEM for specific tests and troubleshooting procedures.

Battery voltage is supplied at all times to the Wiper Motor Relay contacts through Multi-fuse 3 (in the under-hood fuse/relay box). With the ignition switch in ON (II) or START (III) or the engine start/stop switch in ON or START, battery voltage is supplied to the Driver's MICU and the Passenger's MICU through fuse 12 (in the driver's under-dash fuse/relay box). With the ignition switch in ON (II) or START (III) or the engine start/stop switch in ON or START, battery voltage is also supplied to the Wiper Motor Relay coil through fuse 4 (in the driver's under-dash fuse/relay box) and to the Windshield Washer Relay through fuse 3 (in the driver's under-dash fuse/relay box).

Mist

Then the Windshield Wiper Switch is moved to MIST, the signal for mist is communicated to the Driver's MICU. The Driver's MICU provides ground to the Wiper Intermittent Relay coil, energizing the relay. Battery voltage is supplied through the energized Wiper Intermittent Relay and the static Wiper High/Low Relay to the high winding of the Windshield Wiper Motor, causing the motor to run in high. As soon as the motor starts running, the mechanical park/run switch built into the motor will move from PARK to RUN. With the motor running, the mechanical park/run switch is in RUN, removing ground from the motor input to the Driver's MICU. If the switch is held in MIST for multiple wiper cycles, the PARK/RUN switch will alternate between PARK and RUN, indicating what position the wipers are in to the Driver's MICU.

Intermittent

When the Windshield Wiper Switch is moved to INTERMITTENT, the signal for intermittent and the signal for the intermittent dwell time controller are input to the Driver's MICU. The Driver's MICU provides ground to the Wiper Intermittent Relay coil and the Wiper High/Low Relay coil, energizing the relays. Battery voltage is supplied through the energized Wiper Intermittent Relay and the energized Wiper High/Low Relay to the low winding of the Windshield Wiper Motor, causing the motor to run in low. As soon as the motor starts running, the mechanical park/run switch built into the motor will move from PARK to RUN. With the motor running, the mechanical park/run switch is in RUN, removing ground from the motor input to the Driver's MICU. If the switch is in INTERMITTENT for multiple wiper cycles, the PARK/RUN switch will alternate between PARK and RUN, indicating what position the wipers are in to the Driver's MICU.

Low Speed

When the Windshield Wiper Switch is moved to LOW, the signal for low is communicated to the Driver's MICU. The Driver's MICU provides ground to the Wiper Intermittent Relay coil and the Wiper High/Low Relay coil, energizing the relays. Battery voltage is supplied through the energized Wiper Intermittent Relay and the energized Wiper High/Low Relay to the low winding of the Windshield Wiper Motor, causing the motor to run in low. As soon as the motor starts running, the mechanical park/run switch built into the motor will move from PARK to RUN. With the motor running, the mechanical park/run switch is in RUN, removing ground from the motor input to the Driver's MICU. If the switch is in LOW for multiple wiper cycles, the PARK/RUN switch will alternate between PARK and RUN, indicating what position the wipers are in to the Driver's MICU.

When the Windshield Wiper Switch is moved to OFF, the signal for off is communicated to the Driver's MICU. Once the wipers reach the PARK position, the Driver's MICU removes the ground from the Wiper Intermittent Relay, de-energizing the relay. De-energizing the Wiper Intermittent Relay removes battery voltage from the Windshield Wiper Motor.

High Speed

When the Windshield Wiper Switch is moved to HIGH, the signal for high is communicated to the Driver's MICU. The Driver's MICU provides ground to the Wiper Intermittent Relay coil, energizing the relay. Battery voltage is supplied through the energized Wiper Intermittent Relay and the static Wiper High/Low Relay to the high winding of the Windshield Wiper Motor, causing the motor to run in high. As soon as the motor starts running, the mechanical park/run switch built into the motor will move from PARK to RUN. With the motor running, the mechanical park/run switch is in RUN, removing ground from the motor input to the Driver's MICU. If the switch is in HIGH for multiple wiper cycles, the PARK/RUN switch will alternate between PARK and RUN, indicating what position the wipers are in to the Driver's MICU.

When the Windshield Wiper Switch is moved to OFF, the signal for off is communicated to the Driver's MICU. Once the wipers reach the PARK position, the Driver's MICU removes the ground from the Wiper Intermittent Relay, de-energizing the relay. De-energizing the Wiper Intermittent Relay removes battery voltage from the Windshield Wiper Motor.

Washer

When the Windshield Washer Switch is moved to WASH, the signal for wash is communicated to the Driver's MICU. The Driver's MICU communicates the wash signal via B-CAN to the Passenger's MICU. The Passenger's MICU provides ground to the Windshield Washer Relay coil, energizing the relay. Battery voltage is supplied through the energized Windshield Washer Relay to the Windshield Washer Motor, causing the motor to pump washer fluid onto the windshield. Meanwhile, the Driver's MICU provides ground to the Intermittent Wiper Relay coil and the Wiper High/Low Relay coil, energizing the relays. Battery voltage is supplied through the energized Wiper Intermittent Relay and the Wiper High/Low Relay to the low winding of the Windshield Wiper Motor, causing the motor to run in low. As soon as the motor starts running, the mechanical park/run switch built into the motor will move from PARK to RUN.

Headlights Circuit Diagram (Page 110-2). Scheme 228

Headlights Circuit Diagram (Page 110-3). Scheme 229

How the Headlights Circuit Works

The Headlights circuit is composed of the Driver's MICU, the Passenger's MICU, the Headlight Switch, the Dimmer/Flash-to-Pass Switch, the Left and Right Headlights, and the High Beam Indicator. The Driver's MICU and Passenger's MICU control the Headlights with built-in Low and High Beam Control Circuits based upon the position of the Headlight Switch and the Dimmer/Flash-to-Pass Switch. The Driver's MICU and the Passenger's MICU communicate Headlights information directly between each other and via B-CAN.

Low Beams

When the Headlight Switch is moved to the ON position with the Dimmer/Flash-to-Pass Switch in the LOW position, a ground signal is supplied to terminal R8 of the Driver's MICU. The Driver's MICU activates the Low Beam Control Circuit, supplying battery voltage to the Low Beam of the Left Headlight, causing it to come on. The Driver's MICU also sends a message to the Passenger's MICU via the B-CAN communication lines. The Passenger's MICU then activates the Low Beam Control Circuit, supplying battery voltage to the Low Beam of the Right Headlight, causing it to come on.

High Beams

When the Headlight Switch is moved to the ON position with the Dimmer/Flash-to-Pass Switch in the HIGH position, ground signals are supplied to terminals R8 and R22 of the Driver's MICU. The Driver's MICU and the Passenger's MICU activate their Low and High Beam Control Circuits, supplying battery voltage to the Low and High Beam Headlights, causing them to come on.

Flash-to-Pass

When the Dimmer/Flash-to-Pass Switch is moved to the PASSING position, a ground signal is supplied to terminal R21 of the Driver's MICU. The Driver's MICU and the Passenger's MICU activate their Low and High Beam Control Circuits for as long as the switch is held, supplying battery voltage to the Low and High Beam Headlights, causing them to come on.

Daytime Running Lights (DRL)

The DRL circuit is composed of the Driver's MICU, the Passenger's MICU, the Left and Right Daytime Running Lights (built into the Headlights), the Parking Brake Switch, and the DRL Indicator. The DRL circuit operates with the Ignition Switch in ON (II) or the Engine Start/Stop Switch is pressed to select the ON mode, the Headlights off (Headlight Switch in OFF or in PARKING position), and the Parking Brake released.

When the DRL circuit is on, the Driver's MICU and the Passenger's MICU activate their Daytime Running Lights Control Circuits on and off (duty cycle), which provides a reduced voltage (approximately 6-8 volts) to the Daytime Running Lights through Fuse 28 (in the Driver's Under-dash Fuse/Relay Box and Fuse 1 (in the Passenger's Under-dash Fuse/Relay Box). This reduced voltage causes the Daytime Running Lights to come on. The DRL Indicator also illuminates.

Note. The DRL circuit is disabled when the Ignition Switch is turned to OFF (0) or the Engine Start/Stop switch is pressed to select OFF mode. To keep the DRL circuit from coming on, apply the Parking Brake while the Ignition Switch is in OFF (0) or the Engine Start/Stop Switch in OFF. When the Ignition Switch is turned back to ON (II) or the Engine Start/Stop Switch is in ON, the DRL circuit will not come on until the Parking Brake is released. The Headlights revert back to normal operation when the Headlight Switch is moved to the ON position.

Automatic Lighting (Automatic Lighting)

When the Headlight Switch is in the AUTO position, the Driver's MICU and Passenger's MICU receive an automatic lighting signal. When the Automatic Lighting Sensor detects low ambient light, a lights-on signal is transmitted to the Driver's MICU and the Passenger's MICU. The Driver's MICU and the Passenger's MICU activate their Low Beam Control Circuits, supplying battery voltage to the Low Beam Headlights, causing them to come on.

According to the switch request, the Driver's MICU and Passenger's MICU control a series of relays which provide power and ground to the reversible electric door lock motors for lock and unlock modes.

Pressing the UNLOCK button one time will command the Driver's MICU to unlock the driver's door. Pressing the unlock button a second time will command the Driver's MICU and Passenger's MICU to unlock the remaining doors.

Pressing the LOCK button will command the Driver's MICU and Passenger's MICU to lock all of the doors.

Panic Mode

Pressing and holding the PANIC button on the Keyless Transmitter for 2 seconds will activate the panic mode feature. The panic mode command is received by the Immobilizer-Keyless Control Unit. The Immobilizer-Keyless Control Unit communicates the panic mode command to the Driver's MICU and Passenger's MICU via B-CAN.

According to the request, the Driver's MICU and Passenger's MICU sound the horns and flash the exterior lights for approximately 20 seconds. The panic mode can be cancelled by pressing any button on the Keyless Transmitter or by turning the ignition switch to the ON (II) position or the engine start/stop switch to ON. If the ignition switch is in the ON (II) position or the engine start/stop switch is in ON mode, the panic mode cannot be activated.

Security System

The security system will arm automatically when the tailgate and hood are closed, the key is removed from the ignition switch or the remote is removed from the remote slot, and all of the doors are closed and locked.

The security system monitors the following signals

1. B-CAN Communication Lines
2. Door Lock Knob Switches
3. Engine Start/Stop Switch
4. Hood Switch
5. Ignition Switch
6. Power Tailgate Closer Unit Full Latch Switch

When the security system is activated, the Driver's MICU and Passenger's MICU sound the horns and flash the exterior lights for approximately 2 minutes. The security system can be deactivated by unlocking the driver's door with the key or by pressing the UNLOCK button on the Keyless Transmitter, or by grabbing either the driver's or front passenger's door handle with the keyless access remote in range.

Refer to the KEYLESS/POWER DOOR LOCKS/SECURITY SYSTEM for specific tests and troubleshooting procedures.

The immobilizer system is designed to prevent the vehicle from being started without the owner's ignition key. If an attempt is made to start the vehicle with any other key, the immobilizer system disables it from starting.

If the proper ignition key is used, the immobilizer-keyless control unit sends a coded signal to the PCM and Driver's MICU and quickly flashes the immobilizer system indicator LED. The coded signal informs the PCM that the proper ignition key is being used. The PCM grounds the Fuel Pump Relay, energizing it to provide power to the fuel pump. Following the first 2 seconds after the ignition switch is turned to ON (II) with the proper ignition key, the immobilizer system indicator LED turns off, and the engine will run under normal operating conditions.

Battery voltage is supplied at all times through fuse 15 (in the under-hood fuse/relay box) to the immobilizer-keyless control unit and the gauge control module. With the ignition switch in ON (II) or START (III), the immobilizer-keyless control unit and the PCM receive battery voltage through fuse 9 (in the driver's under-dash fuse/relay box).

1. When the ignition switch is turned ON (II) and a programmed immobilizer code is identified, the immobilizer indicator quickly flashes once.
2. The immobilizer system will allow the engine to start normally.
3. When the ignition switch is turned OFF (0), the immobilizer indicator does not come on.

Immobilizer System Detects a Problem

1. When the ignition switch is turned ON (II), and a programmed immobilizer code is not identified, the immobilizer indicator quickly flashes once and then blinks continuously.
2. The immobilizer system results will vary depending on how quickly the key is turned. If the key is turned quickly from the OFF (0) position to the START (III) position, the engine will start and run for approximately 1 second and shut off. If the key is turned to the ON (II) position, delayed there, and then turned to START (III) position, the starter will turn the motor over, but it will not start.
3. When the ignition switch is turned OFF (0), the immobilizer indicator will blink ten times then go off to indicate the system is correctly reset.

Refer to the IMMOBILIZER SYSTEM for specific tests and troubleshooting procedures.

Key Interlock

When the Ignition Key is inserted into the Ignition Switch, a ground signal is provided to the Driver's MICU. The Driver's MICU detects the insertion of the Ignition Key through this input. If the shift lever is out of PARK, a ground signal is provided to the Driver's MICU. The Driver's MICU detects that the shift lever is out of PARK through this input. The Driver's MICU provides ground to the Key Interlock Solenoid. The Key Interlock Solenoid is then energized, which prevents the Ignition Switch from being turned to LOCK (0).

Shift Position Interlock

Battery voltage is supplied at all times through Fuse 10 (in the under-hood fuse/relay box) to the Brake Pedal Position Switch. With the Ignition Switch in ON (II) or START (III), battery voltage is supplied through Fuse 18 (in the driver's under-dash fuse/relay box) to the Shift Lock Solenoid. When the brake pedal is pressed, a battery voltage input is supplied to the PCM and the Driver's MICU. If, at the same time, the accelerator pedal is not pressed, the PCM provides ground to the Shift Lock Solenoid. The Shift Lock Solenoid is then energized, allowing the shift lever to be moved from the PARK position.

While the vehicle is in forward motion, the PCM removes ground from the Shift Lock Solenoid. The Shift Lock Solenoid is then de-energized, which disables the shift lever from being moved to REVERSE or PARK.

Refer to the A/T INTERLOCK SYSTEM for specific tests and troubleshooting procedures.

Battery voltage is supplied at all times through fuse 18 (in the passenger's under-dash fuse/relay box) to the driver's power lumbar support switch.

Raise Lumbar Support

When the lumbar support switch is moved to FORWARD, battery voltage is supplied to the lumbar support motor through the lumbar support switch. The lumbar support motor is grounded through the opposite contact of the lumbar support switch. The motor will run until the switch is released or the lumbar support reaches the full forward position.

Lower Lumbar Support

When the lumbar support switch is moved to BACKWARD, battery voltage is supplied to the lumbar support motor through the lumbar support switch. The lumbar support motor is grounded through the opposite contact of the lumbar support switch. The motor will run until the switch is released or the lumbar support reaches the full backward position.

Refer to the POWER SEATS for specific tests and troubleshooting procedures.

Battery voltage is provided at all times through fuses 8 and 9 (in the passenger's under-dash fuse/relay box) to the front passenger's power seat adjustment switch.

Front Up-Down

When the front up-down switch is moved to DOWN, battery voltage is supplied to the front up-down motor through the driver's power seat adjustment switch. The front up-down motor is grounded through the UP contact of the front up-down switch. The motor will run until the switch is released or the seat reaches the full front down position. The contacts for UP operation of the front up-down switch are wired the opposite way of the DOWN contacts, causing the motor to run in the opposite direction.

Slide

Slide operation is similar to the front up-down operation.

Recline

Recline operation is similar to the front up-down operation.

Refer to the POWER SEATS for specific tests and troubleshooting procedures.

In the driving position memory system, the driver's seat, the tilt/telescopic steering, and the power mirrors have a memory feature. The four driver's seat adjustments (forward and back, front up and down, rear up and down, and seat back angle), the steering tilt and telescopic adjustments, and the power mirror adjustments can be regulated separately. All of the adjustments can be memorized at the same time by pressing the SET button of the driving position memory switch, and then (within 5 seconds) pressing one of the two position buttons. If the same position button is pressed after the adjustments are memorized, the seat, the steering, and the mirrors will move to the memorized positions.

Note. Disconnecting the battery will cancel the memorized positions.

The driving position memory system is directly connected to the remote transmitters 1 and 2. When the doors are unlocked using either the remote transmitter 1 or remote transmitter 2, the corresponding memory position 1 or 2 is activated.

Power Seat Position Sensors

Each driver's power seat motor has a corresponding sensor, which sends a pulse to the power seat control unit when the motor rotates. The power seat control unit then stores the number of pulses for that seat position in its memory.

Power Tilt/Telescopic Steering Position Sensors

The power tilt/telescopic steering control unit uses input from a tilt position sensor and a telescopic position sensor to detect voltage changes caused by the movements of the steering. The power tilt/telescopic steering control unit stores the voltage changes for each driving position in its memory.

Power Mirror Position Sensors

Each power mirror has a tilt position sensor and a swing position sensor to detect the changes in voltage caused by the movements of the mirror. The power mirror control unit then stores the voltage changes for that mirror's position in its memory.

Reverse Mirror Control

When the transmission is shifted into reverse with the mirror selection switch in LEFT or RIGHT, the corresponding mirror tilts down automatically. If the mirror selection switch is in the neutral position, the reverse mirror control is disabled. When the transmission is shifted out of reverse, the tilted mirror will return to its previous position.

Refer to the DRIVER POSITION MEMORY SYSTEM (DPMS) for specific tests and troubleshooting procedures.
